  The MIRROR_HOST environment variable can be used to change the
  apt-cacher host.  It should be something that the target VM can
  resolve.  It may be set to 127.0.0.1, in which case it will be
  changed to 10.0.2.2 on the guest.  10.0.2.2 is the host IP as visible
  from the guest under qemu networking.
